Timer display to countdown

Question

right now I have my timer displaying seconds, what can I add to it to display the time in a 0:00 format?

new CountDownTimer((300 * 1000), 1000) {

                         public void onTick(long millisUntilFinished) {
                             mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
                         }

                         public void onFinish() {
                             mTextField.setText("Session Completed!");
                         }
                      }.start();

Answer 1

Try this:

Date date = new Date((300 * 1000)* 1000);
SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss");
String dateFormatted = formatter.format(date);

You can also use

SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss:SSS");

Answer 2

@Override
public void onTick(long millisUntilFinished) {
 long temp_long = millisUntilFinished / 1000;

 second = temp_long % 60;
 hour = temp_long / 3600;
 minute = (temp_long / 60) % 60;
 String tempTimer;

 tempTimer = ((hour < 10) ? "0" + hour : "" + hour)+ ((minute < 10) ? ":0" + minute : ":"+ minute)+ ((second < 10) ? ":0" + second : ":" + second);

 mTextField.setText(tempTimer);
}

You can use android Chronometer to display countdown.
